Six pentagons are interlinked, making a beautiful pendant. In the shape you may also recognize an
Icosidodecahedron. Although it does not appear so, the pentagons overlap slightly and will be fused together into a single object. This is one of the "orderly tangles" discovered by Alan Holden in the 1970's. Each pair of pentagons is linked. The strut diameter is 2 mm, pentagon edge length is 14 mm.
